Why do I always seem to get hurt by every guy💔

Soo I’ve been in a relationship for almost 3 years and he’s always hurting me and disrespecting me. I don’t remember the last time I was even happy💔 I do everything for myself and my six year old daughter...Sometimes I feel what I’m doing isn’t enough. I cook , I clean, I wash clothes, I’m always pleasing everyone around me and making sure everyone is okay...But nobody is there for me..I’m currently out of work on workers comp. and that’s barely getting me by. I’m constantly stressed out..My boyfriend doesn’t help me. I found him a job a few months ago. And he doesn’t try to help around the house. I don’t ask for anything but for him to be honest and faithful and love me because I’ve never been loved or appreciated..He doesn’t take me out . He says I have to wait until I get some clothes and get my hair and nails done. We haven’t been anywhere in the last two years. This year he has cheated on me numerous of times. I took him back each time. I know I’m dumb. I feel dumb. But why do I care so much to try to make something work ? He disrespects me in front of my daughter. My daughter feels that I’m not happy and something’s wrong with me. As much as I try to hide it sometimes I can’t. I cry myself to sleep every night asking God why me. I’m a loving person I don’t do anything wrong to people. I will give my last to a stranger. Why can’t I just be happy? I’ve tried talking to my boyfriend and telling him how I feel and what I expect but he only listens for the time being..Then he goes back to his Narcissistic ways...I’m beginning to feel like I’m a failure and worthless. I’ve thought about suicide plenty of times. But each time I thought about it I’ve thought of my daughter. She needs me. Sometimes he make me feel so ugly and worthless that I start to believe it. I never had insecurities but since I’ve met him I’ve realized how bad my insecurities have gotten. I just want to be happy and feel loved. I want the same love and care I give to people. I don’t know what to do...
